Puritans formed "covenant communities" which were centered around their religion. Often times, the small communities would have a building which functioned as a church and a courthouse. These communities were often formed in New England, where agriculture was sparse, so the people would rely on trade in ports like Boston and Philidelphia to bring them income, along with carpentry, shipbuilding, etc. Often times, the Puritans were very intolerant of those who did not share their faith, and like the later Cult of Domesticity, believed in masculine supremacy, leaving the women to tend to children, cook, clean, etc.
